Jurph points out (correctly) that people usually spell it out (like M R S degree) so it sounds like the abreviations of other more standard degrees.

Now that the trend in middle class families is to have both partners working this is probably a less common situation. There was a time however when it was fairly normal for parents with money to send their daughters to college with the expectation that they'd finish with some unimportant degree and marry an up and comingdoctor or lawyer or somebody like that when they graduated.
